Taqiyya

Taqiya (تقیة, taqiyyah/ taqīyah, literally "prudence, fear, caution") is an Islamic term referring to precautionary dissimulation or denial of religious belief and practice in the face of persecution. This practice is emphasized in Shia Islam whereby adherents are permitted to conceal their religion when under threat of persecution or compulsion. However, it is also permitted in Sunni Islam under certain circumstances.

Any one who, after accepting faith in Allah, utters Unbelief,- except under compulsion, his heart remaining firm in Faith - but such as open their breast to Unbelief, on them is Wrath from Allah, and theirs will be a dreadful Penalty.

Let not the believers Take for friends or helpers Unbelievers rather than believers: if any do that, in nothing will there be help from Allah: except by way of precaution, that ye may Guard yourselves from them. But Allah cautions you (To remember) Himself; for the final goal is to Allah.
